Mechanical Properties And Thermal
Characteristics Of Sandwich Composite
Panel From Spent Mushroom Substrate And
Empty Fruit Bunch Fibers Towards Heat
Insulation Application.
PhD thesis, Universiti Sains Malaysia.
Abstract
The growing demand for eco-friendly products and materials has prompted several
studies on the potentials of natural waste fiber such as coconut husk and sugarcane bagasse
as composite panels towards heat insulation application. However, research on composite
panels fabricated of the spent mushroom substrate (SMS) and empty fruit bunch (EFB)
fibers for insulating purposes is limited
properties and thermal characteristic, controlled by a range of parameters. Thus, only a
few research have looked at the impact parameters of fiber ratio and fibrillation degree.
There are less researcher concentrated on the fabrication process using sandwich
composite approach. Therefore, this study aimed to characterize the physico-chemical
properties of SMS and EFB fibers towards sandwich composite panel fabrication process;
to evaluate the properties and thermal characteristic of the sandwich composite panel at
different SMS and EFB fibers ratios and; to assess the effect of EFB fiber fibrillation
degree on its properties and thermal characteristic. To achieve these objectives, the SMS
and EFB fibers physico-chemical properties in terms of chemical composition, particle
size and thermal degradation temperature were characterized and compared with fresh
rubberwood sawdust (FRS) fiber
